Title: Improvements in or relating to platen printing presses
IPC: B41F1/08
Filed: 1926-03-04
Abstract: 264,683. Hartmann, C. W. March 4, 1926. Feeding webs.-A web platen press can print superimposed impressions on the web, or can be arranged to print spaced identical impressions at double the speed. An adjustable roller is arranged between the two printing-couples. The web is fed from a roll 52 by rollers 51, passes into a loop 150, and over guide rollers 82, 81 to the first platen 47. Between two platens 47 an adjustable roller 16 carried by 'slides 17 is arranged, the slides being adjustable by screws operated by bevel wheels actuated by a handle 23. The handle is fixed on a shaft 22 provided with a bevel wheel at one end, and is detachably connected by a pin 24 to another bevel wheel, so that one end of roller 16 can be raised or lowered independently of the other. After printing, the web is fed away by intermittently driven rollers 53. The rollers 51 are driven bv bevel gearing from the main drive shaft 12, Fig. 2, and a change-speed gear 57, and by conical pulleys and an adjustable belt. The rollers 53 are driven intermittently and adjustably by means of a gear sector 66 which is oscillated by an adjustable crank-pin on a disc 65 driven by gearing from the shaft 58 of pulley 60. The sector 66 drives the rollers 53 through a free-wheel drive. The printing-surfaces are, adjustable laterally on beds carried by oscillating frames 30 pivoted at 31 to box-like frames 10. The frames 30 are oscillated by rods 28 and cranks driven from shaft 12, and the beds are moved alternately into printing position. The printed web may be wound on a roll or cut into sheets. Delivery apparatus; cutting-apparatus.-The shear cutter for cutting the printed web into sheets, and the oscillating flyer for delivering the cut sheets to a table 83, are mounted on a slide adjustable by a screw 79 operated by a wheel 81. The operating-mechanisms for the cutter and fiver are splined to their shafts to permit of the adjustment being effected without disturbing the driving-connection.

Title: A spool having means for retaining fixed to its core a perforated photographic film
IPC: G03B17/30
Filed: 1948-02-27
Abstract: 653,751. Photographic and kinematographic film spools. DUCATI-SOC. SCIENTIFICA RADIO BREVETTI DUCATI. Feb. 27, 1948, No. 6162. Convention date, Nov. 12, 1946. [Classes 97 (i) and 98 (i)] A film spool of the kind in which perforated film is attached to the spool core by engaging the perforations upon teeth extending outwards from the outer surface of the core is characterized in that the film is retained on the teeth by a strip or spring carried by the core and partially surrounding it. In an alternative construction the teeth are formed on and extend inwardly from the inner surface of the strip. As shown a preferably resilient strip 4 partially surrounds the spool core 1 and is prevented from rotating about it in one direction by a stop 2. Teeth as 3, 3<SP>1</SP>, are formed in the outer surface of the core or the inner face of the strip and engage in the film-feed perforations 6 as the film is pushed between the core and the strip, return movement of the film being prevented by the vertical face of the sawtooth profile of the teeth engaging the back edge of the perforations. To remove the stump of film held on the spool after cutting off the free portion of the film the strip 4, (Fig. 2) is rotated anticlockwise and the stump of film freed so that the spool may be used again. In the alternative construction, Fig. 3, having teeth formed on the inner face of the strip, the strip is rotated until it and the film stump have passed completely over the inclined face of the stop 2, the film is pressed down into the space between the strip and the core, and is then removed from beneath the end of the strip opposite to that under which it was inserted originally.

Title: Device for examination by means of ultrasonic vibrations
IPC: A61B8/00
Filed: 1975-02-17
Abstract: 1491527 Ultrasonic inspection PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd 17 Feb 1975 [20 Feb 1974] 6543/73 Heading G1G A device for the ultrasonic examination of a cross-sectional plane P through an object comprises a line of transmit transducers each having a transmission direction in the plane P, and a plurality of pairs of receive transducers with the receive directions of the two transducers of a pair being situated in a plane P<SP>1</SP> which is perpendicular to both the line of transmit transducers and to the plane P. The transmit transducers are pulsed in turn and, following each transmission pulse, selected receiver pairs are operative in sequence to supply echo pulses to a unit which displays an image of the examined cross-section. In the Fig. 2 embodiment a flat mosaic of transmit transducers el - - - em and receive transducers r1A(1) - rrB(m) is used. In any column of the mosaic the two receive transducers equidistant from the line of transmit transducers form a pair (e.g. r2A(1) and r2B(1)) and are connected to a common terminal (t11 --- trm). Unit B provides pulses ae for controlling at DA the selection of transducers el - - - em in turn. The selected transducer is pulsed r times by generator G. The pulse interval is sufficient to allow spurious multiple echoes to die away. After each transmission pulse, multi-plexers MA1 --- MAm controlled by "row address" pulses al sample the echo signals and a unit DU passes the samples from a selected group of columns of receive transducers to the beam intensity control W of a CRT. The group typically comprises fifteen columns, extending to the seventh column either side of the active transmit transducer. The CRT X-scan and Y-scan are synchronized with the transmit transducer selection and pulsing and with the sampling of the echo signals. In a modification Fig. 3 (not shown) the multi-plexers are omitted, each column of receive transducers being used as a phased array with the signals from its transducer pairs being brought into phase and summed for application to unit DU. The line of transmit transducers need not be coplanar with the receive transducers.

Abstract: 1,208,082. Charging and discharging secondary batteries. OLDHAM & SON Ltd. 7 Feb., 1969 [2 May, 1968], No. 6838/69. Heading H1B. [Also in Division H2] A sealed secondary battery is taken through a plurality of discharge-charge cycles without maintainance by allowing evolved gases to collect in a gas space forming part of the battery where controlled stoichiometric recombination occurs and regulating the pressure within said space by an automatic pressure relief valve so that residual gas representing deviations from stoichiometry during one cycle is retained and recombined with gas representing deviations from stoichiometry in other cycles. A particular embodiment involves a miners lamp battery, Fig. 3, in which hydrogen and oxygen are evolved during use. The battery comprises 2 cells each including positive and negative plates 232 arid 236 and separators 234 and 240 contained in a polycarbonate case capable of retaining pressures up to 80 p.s.i.g. Gases evolved collect in catalyst housing 244 where they are combined by a catalyst comprising pellets of palladium coated alumina held on a cylindrical support and surrounded by glass beads to control the rate at which the gases reach the catalyst and consequently prevent overheating. The pressure inside the case is controlled by relief valve V. Alternatively the rate of recombination may be controlled by reducing the efficiency of the catalyst or the recombination means may be a hot wire of controlled temperature. The battery may be evacuated before use.
